(Devarim 12:7) "And you shall eat there before the L-rd your G-d": It is found that there were two precincts (for eating), one for holy of holies, and one for lower-order offerings.
"and you shall rejoice": It is written here "rejoicing," and, elsewhere (27:7) "rejoicing." Just as the "rejoicing" there is with peace-offerings, so, the "rejoicing" here.
(דברים יב ז) וַאֲכַלְתֶּם שָׁם לִפְנֵי ה׳ אֱלֹהֵיכֶם – בַּמְּחִיצָה.
(Devarim 12:7) "And you shall eat there before the L-rd your G-d": It is found that there were two precincts (for eating), one for holy of holies, and one for lower-order offerings.
וּשְׂמַחְתֶּם, נֶאֱמַר כָּאן שִׂמְחָה, וְנֶאֱמַר לְהַלָּן (דברים כז ז) שִׂמְחָה. מָה שִׂמְחָה הָאֲמוּרָה לְהַלָּן – שְׁלָמִים, אַף שִׂמְחָה הָאֲמוּרָה כָּאן – שְׁלָמִים.
"and you shall rejoice": It is written here "rejoicing," and, elsewhere (27:7) "rejoicing." Just as the "rejoicing" there is with peace-offerings, so, the "rejoicing" here.
בְּכָל מִשְׁלַח יֶדְכֶם, בְּכָל מַה שֶׁאַתֶּם שׁוֹלְחִים בּוֹ יְדֵיכֶם – בְּרָכָה אֶשְׁלַח בּוֹ.
"in all to which you put your hands": In all to which you put your hands, I shall place blessing in it.
אַתֶּם וּבָתֵּיכֶם – זוֹ אִשְׁתּוֹ.
"you and your households": "house" — his wife.
אֲשֶׁר בֵּרַכְךָ ה׳ אֱלֹהֶיךָ – הַכֹּל לְפִי הַבְּרָכָה הָבֵא.
"whereby the L-rd your G-d has blessed you": all according to the blessing which comes (as "vows and gifts" [6]).
